EDMOND LAMOUREUX, OF WOONSOOKET, RHODE ISLAND, ASSIGNOR OF VILLE, RHODE ISLAND.

FLOAT-DETECTING SHUTTLE.

SPECIFICATION forming part of Letters Patent No. 754,658, dated March 15, 1904.

Application filed August 12, 1903. Serial No. 169,270. (No model.)

To all whom it may concern:

Be it known that I, EDMOND LAMoUREUX,a citizen of the United States, residing at Woonsocket, in the county of Providence and State 5 of Rhode Island, have invented a new and useful Improvementin Float-Detecting Shuttles, of which the following is a specification.

This invention relates to certain new and useful improvements in shuttles, and more I especially to that classknown in the art as float-detecting. It has for its objects, among others, to provide a simple and cheap shuttle of this character in which the float-detecting I mechanism shall be composed of few parts,

I those compact, readily applied to a shuttle,

and positive and reliable in operation.

Other objects and advantages of the invention will hereinafter appear and the novel features thereof will be specifically defined by the appended claims.

' The invention in its preferred forms is clearly illustrated in the accompanying drawings, which, with the numerals of reference marked thereon, form a part of this specifica- 5 tion, and in which Figure l is a perspective view ofa portion of a shuttle, showing the present improve ments applied. Fig. 2 is a view looking at the outer face of the plate. which carries the im- 3 provement, removed. Fig. 3 is a similar View showinga slightly-modified form of construction. Fig. 4 is aperspective view of the oscillating arm shown in Fig. 2 removed. Fig. 5 is a vertical cross-section through the line 5 5 of Fig. 2. Fig. 6 is a vertical section on the line 6 6 of Fig. 3. Fig. 7 is an end view of Fig. 2. Fig.8 isaperspective view of amodified form of oscillating arm.

Like numerals of reference indicate like 4 parts throughout the several views.

As the present invention does not pertain to the shuttle proper nor the manner of holding the bobbin therein, nor to other parts except the float-detecting mechanism, an illus-' tration or description of such parts, farther than is necessary to clearly explaining the mode of application and use of the present invention, is not deemed necessary. It is to be understood, therefore, that such parts as are not herein illustrated and with which the features forming the subject-matter of the invention cooperate may be of any well-known or approved form of construction.

Referring then to the details as illustrated, 1 designates a portion of a shuttle having the usual openings 2 and 3 for the passage of the yarn, which is threaded therethrough in the usual manner.

4 is a plate adapted to be removably secured to the inner face of the side wall of the shuttle in any suitable manner. The face of this plate adjacent the said inner face of the side wall of the shuttle is formed with a recess, chamber, or cavity 5, as seen clearly in Fig. 2, and within this chamber is pivotally mounted on a suitable pin or other support 6 the float-detecting lever or oscillating twoarmed member 7 which comprises the main or body portion 8 and the spring-arms 9 and 10, extending from the upper end thereof and normally curved or bent outward, as seen in Fig. 2, and their free ends bearing against the opposite walls of the chamber or cavity,

as shown. The body portion is provided with a tailpiece or extension 11, which depends below the pivot, as shown, and is designed to serve a purpose which will soon be explained.

12 is an oscillating member or arm having at a point intermediate its ends a cam projection or the like 13, which is designed for cooperation with the tailpiece 11 of the member 7, as seen in Figs. 2 and 3.

In the form shown in Figs. 2 and 4, 5 and 7 this member 12 has at one end a long arm 14, extending at substantially a right angle to its length and provided with a notch or hook or the like 15 and at the other end a short arm 16, also at right angles to the length of the member. This member is seated in. a groove or recess 17 in the bottom edge of the plate 4, with its long arm 14 normally located in a vertical groove 18 in the inner face of the plate, the short arm 16 being disposed at the end of the said plate, as seen in Figs. 2 and 7, and the latter engaged by a spring 19, having its upper end held in any suitable manner in the end of said plate, as shown in Fig. 2.

In the form shown in Figs. 6 and 8 the construction is substantially the same except that the short arm of the member 12 is omitted, the long arm 14 and the notch or hook 15 and the lug or extension 13 all being present. In this form instead of having the spring at the end of the plate to engage the short arm of the member a spring 21 is employed, which is located in the recess or groove 18 and bearing against the back of the long arm 14:, as show in Fig. 6.

The operation will be readily understood from the foregoing description when taken in connection with the annexed drawings, and a further detailed description thereof does not seem necessary. The yarn 20 is led from the bobbin through the holes 2 and 3 and in the path of the long arm of the member 12, as shown. hen a floating warp thread engages the float-detecting lever 7 and rocks it on its pivot 6, the lower end of such lever 7 is moved slightly to one side of the cam projection 13. When the lever 7 thus releases the cam projection, the spring 19 suddenly forces the arm 14: into engagement with the end of the spindle, whereby the thread is caught and broken.

The operation is substantially the same, whether the spring and form seen in Fig. 2 or that shown in Fig. 3 be employed.

It is to be understood that the short lug 13 or 13 works through a slot 22 in the lower edge of the plate 4.

From the above it will be evident that I have devised a novel form of float-detecting shuttle, and while the forms of embodiment herein illustrated are what I at present consider the preferable ones it is evident that changes, variations, and modifications may be resorted to without departing from the spirit of the invention or sacrificing any of its advantages, and I therefore do not wish to be limited to the details herein disclosed.

What is claimed as new is 1. A shuttle having a removable plate attached to its inner wall and having avertical groove, an oscillatory member having an arm located in said groove, a pivoted float-detecting member having a tailpiece for engagement with the oscillatory member, and a spring acting upon the first member.

2. A shuttle provided with a detachable plate having a cavity and vertical groove, a pivoted float-detecting member in said cavity and having spring-arms, an oscillatory member having an arm movable in said groove, and a spring held in said plate and adapted to cooperate with said oscillatory member.

3. A shuttle, a plate attached to the inner wall thereof and having a cavity and a groove, a pivoted float-detecting member in said cavity and having spring-arms and a tailpiece, an oscillatory member having a lug for engagement with the tailpiece, a long arm seated normally in said groove, and a spring for actuating said member when the same is disengaged from the other member.

4. A shuttle having a plate attached to its inner wall and provided with a cavity and a vertical groove and a longitudinal groove in its under edge, a float-detecting member pivoted in said cavity and having a body portion, tailpiece and spring-arms, an oscillatory member seated in said longitudinal groove, and having a long arm seated in the vertical groove and a cam projection cooperating with said tailpiece, and a spring held in said plate, as and for the purpose specified.

In witness whereof I have hereunto set my hand in the presence of two witnesses.

EDMOND LAMOUREUX.
